INNERSOLE FOR BOOTS AND SHOES.

Specification of Letters Patent.

Patented July 2, 1907.

Y Application filed November 14,1906. Serial No. 343,362-

To all whom it may concern:-

Be it known that I, Fnnoneron Onnm BROWN, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Innersoles for Boots and Shoes; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others. skilled in" theart to which it appertains to make and use the same.

This invention relates to a hygienic cushion inner sole for boots and shoes, composed of canvas, felt, calf skin or sheep skin and sole leather, in combination consisting of felt covered and reinforced with canvas by the gem process, the heel being reinforced by the sole leather reinforcing piece immediatelyjunder the felt,

the calf skin or other soft covering extending only to the edge of the sole, the whole combination of materials being'attached or'lastene'd together by stitching around the edge by ordinary commercial shoe stitching machine.

T he object in view is to provide as an integral part of a hoot or shoe a porous, strong and flexible inner sole,

elastic support for the foot; and with these objectsjin View, the inventionconsis ts in the construction illustrated in the accompanying drawings and explained in the following description.

Referring to thisdrawing, Figural is aplan view of the under side of the sole; Fig. 2 is a similar view of the top side; Fig. 3 is a transverse section of the sole in the position it occupies in the shoe; and, Fig. 4 is a per-Z spective of the under side of the heel portion of the sole. In all these figures, (2 denotes a flat, relatively thick sheet of strong felt, preferably that known commer 35. cially as piano v felt. The upper's'ide of this sheet of felt has a covering d of calf skin or other softieather stitched thereto, and the margin of the felt is split edgewise into two parts, 0 and c, asbestshown in Fig. 3, the'part 0 being bent perpendicularly to the plane of 40 the felt, forming a flange or Wale to which the welt and the upper or vampare sewed in a well known manner.

The portion of the sole comprising the heel is rein- :forced with a piece of sole leather h placed between the felt and the covering of calf skin or other soft leather,

45, as best shown in Fig. 4. The under sideof the felt is covered with a layer b of the canvas or other strong tex tile material, and thecanvas also-covers the projecting flange c and the portion 0 of the felt which projects beyond the flange. This canvas cover is cemented to the flat part of the felt inside of theflange, and is moreover cemented to "the flange itself on both sides, so as to stiffen the same and hold itprojecting from the felt, as shown in Figs. 3 and 4. This canvas 'cover is stitched to that portion of the felt inner-sole which is outside of and beyond the shoulder, otherwise known as the flange or wale this outer portion of the felt innersole being 7 known as the featherl so as to stiffen the same and hold it projecting from the felt, as shownin Figs. 3 and4. Y v For the purpose of mhre rigidly uniting the canvas and leather coverings to the felt sole, and especially to prevent the separation ofthese coverings from the projecting edge 0 of the felt, a line of stitching e is passed all the way around the margin just outside of the flange c.

v The construction being as thus described, it is to be. notedthat the'sole has a marked degree of strength and flexibility, combined with asoft yielding and;.elastic l I support for the foot. i

As will he understood by'those skilled in the art, the flange or wale to which the welt and upper are sewed will provide a soft, 'yielding and lSlOfIlled by what is commercially'known as the gem" process, and it ishelieved that the present invention presents the first instance of the combination ofa composite innersole formedof felt inclosed'between a covering of calf skin or soft leather on theupper side with sole leather heel reinforcing, the two coverings being stitched to the felt shoulder only, and extending only ,tothe'cdge of insole and the whole 'heingadditionally A flexible inner sole to form an integral part of a boot or shoe, the same comprising a relativelythick sheet of elastic and porous felthaving its edge slotted to make a perpendicular flange .forining a wale to sew to, a sheet of canvas cemented to the under side of the felt, a covering of thin soft leather secured totlie upper side of the felt. a piece of sole leather secured between the felt and its leather covering at the heeL-and aline of stitching around the edge of the sole'outside of the flange, the stitches extending through the felt, the canvas and leather coverings, and the lieel'reinforcing piece. s

In testimony whereof I afiix my signature, in presence "of two witnesses. I
